Testing of solar panels

Some customer place “void claims” that their solar panels have “poor performance”. In all cases such claims were proved as invalid. The solar panels are professionally tested high quality products. The performance and specification parameters are verified several times before leaving the factory.

To honor the claims of our customers, we may perform additional tests to prove the performance of the solar panels. We use the comparative method. We compare two panels using calibrated (identical) ohmic loads. At the same location at the same sunshine level, the results of the power performance are compared.

The photo shows the test results. The so-called “defective panel” generates 6.26Amp while the nominal panel makes 6.23 Amp.
